What to Wear in Fort Myers in September
September in Fort Myers sits firmly in the thick of Southwest Florida's wet season, with high temperatures averaging 91–93°F and overnight lows staying muggy around 74–76°F. Humidity is relentless, making heat index values regularly feel like 100°F or higher during midday. Afternoon thunderstorms roll in almost daily, typically between 2–5pm, dropping heavy rain quickly before clearing. September is also peak Atlantic hurricane season, so there's a real chance of tropical storms affecting the area. Dress for heat and sudden downpours above all else. Lightweight, moisture-wicking fabrics like linen, bamboo blends, or technical athleisure are your best friends — anything that dries fast and breathes well. Opt for shorts, sundresses, tank tops, and loose linen pants in light colors that won't absorb the brutal sun. Waterproof sandals or quick-dry sneakers are far more practical than leather or canvas shoes that take hours to dry. A compact packable rain jacket or a small umbrella is non-negotiable. Despite the heat, pack one light layer — a cardigan or thin long-sleeve — for air-conditioned restaurants and shops, which are often aggressively cold. Sun protection is critical: UV index regularly hits 10–11, so a wide-brim hat, UV-blocking sunglasses, and reef-safe SPF 50 sunscreen should be daily essentials.
